Limited information indicates benzathine penicillin G produces low levels in milk that are not expected to cause adverse effects in breastfed infants. Occasionally disruption of the infant's gastrointestinal flora, resulting in diarrhea or thrush have been reported with penicillins, but these effects have not been adequately evaluated. Benzathine penicillin G is acceptable in nursing mothers.
有限的信息表明,苄星青霉素G在乳汁中的含量较低,预计不会对母乳喂养的婴儿产生不良反应。偶尔有报道称,青霉素会破坏婴儿的胃肠道菌群,导致腹泻或鹅口疮,但这些影响尚未得到充分评估。哺乳期母亲使用苄星青霉素G是可以接受的。
